Not sure what you mean by understanding reflection but i'll do my best.
World War II was one of / if not the biggest tragedy to happen in modern history. It taught the world important lessons about society; that we need to work together and not let our differences enable another global conflict to the degree of WW2. However, history never completely repeats itself and while WW2 was a terrible and unimaginable tragedy, it provided us with information that can help us all in avoiding a future conflict similar in nature. However, how is the author so certain that history doesn't repeat itself? Have we not seen history do such thing. For example, there were vaccination protests all throughout history just like how there is vaccination protest today. So, I am interested in how the author came to his conclusion that WW2 will not inevitably repeat itself.
